To all whom t may concern .Be it known that I, CHARLES C. STU'rzi,

ilton and State of Ohio, a citizen of the United States, have invented 'or discovered certain new and usefu improvements in.

Manufacture of Glass Articles, of which im provements the following is a specification.

.The invention described herein relates to certain improvements in means for.V the transferlof glass from a furnace t a series of relatively stationary The invention has for its object the charging of a 'series of receptacles `in succession by'a stream iowing constantly from a furnace-or other source of supply, moving i. vthe'reccptacles in succession to a series of suitably arranged molds and charging the latter`in succession.-

The invention is hereinafter more fully described and claimed.` In the accompanying drawings forming a part of this specification, Figure l is a sed tional elevation oi. myimproved apparatus; Fig. 2 is a transverse section on a plane i`n' dicated by the line lil-11, Fig. 1i; Fig. 3

is a top plan view of a portion of the mold operating mechanism showing two adgacent molds. 'y A mold sections and the mechanism for shift-v ing them to and from their companion mol'd sections, which are not shown; Figs. a and 5 are plan and sectional elevations respectively showing the ladle slide, carriageand theguides therefor; Figs. 6 and 7 are de tails showing a vform of mechanism for turning the ladle and locking -it in its normal and inverted position; Fig. 8 isa plan view of aportion of endless chain showing relative positions of hooks thereon; and Fig. 9 is a diagrammatic View showing the arrangevment of the Vtransfer and shaping mechanism relative to the furnace from which the receptacles are charged.

The ladiesv 1 are provided With shaft-s 2 which are rotatably mounted in bearing 3 .on the vertically movable slides e.A These slides are mounted in guides on the carriages 5, which during the charging of the ladles and their movements to the molds andbeyond, are supported by guides 6, extending from a point adjacent. to but below the spout extending from the furnace vor other source of suppl The carriages are moved along the guides. 'byanyy uitable' means, asthe constantly operating endless 8 -and 9, one series for moving the carriages and ladies'v to operative position relative to themolds, and the other series for moving the carriages from such position to a point where their lreturn vto ladle charging posi?" tion will begin. The two series hooks are out of line transversely of the chain as; shown in Figs 5 and 9, and those of the series for moving the ladle from mold charging position are placed a distance from the hooks oi the other series suiiicient to permit the raising and lowering' of the slide and the flow of glass into the mold before they engage and shift the carriage. The hooks 8 engage rollers l0 mounted on the 'vertically movable slides, and as,I the ladles approach position under the melde, rollers 12 mounted on the vertically movable slides, pass onto cam proajections i3,..on

the guides 6' thereby raising the Slides-and the rollers 10 a suiiicient distance toxperf4 mit the hooks to pass under the latter. jfne lifting cam 13 is employed for each meld f of the series, but as. shown in Figv, the several cams are out ct' line transversely t,of the guides 6, and the position of .the rollers l2 on the vertical slides are correspondingly adjusted so'that the slides .will be raised1 only. when the ladles approach the lmdld to be charged therefrom.

As soon as a ladle has stopped in proper relation to a mo d, it is raised, glass is forced therefrom, and again lowered,as will be hereinafter described. After these operfations have been performed, -a hook il en'- gages a pin 141; on the carriage 5, which is their shifted weleens of the guidera, the' hook passing down awayfrom thezpin 14. As a carriage approaches the 4 end ci' the guides, provision'is Inade- Jfor turning the ladle to discharge the remainder of the glass therein. A convenient means for that purpose consists of a toothed Vwheel 15 secured on the ladle shaft 2 and a series of pins 16 on one of the guides 6, as shown in vFig.
